Application filed .Tune 19, 1914.

@o all whom 'it may concern i Be it known that l, ADAM RAMBACHER, citizen ot Germany, residing at Munich, Bfr varia, Germany, have invented certain new and useful Improvements in Means for Preventing the Creeping or" Railway and like Rails; and l do herel'y declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains tojnake and use the same.

The invention relates to means for preventing the creeping of railway and like rails carried in any manner on sleepers.

The im roved clamping device diiiers essentially rom known devices for this purpose by the fact that it has a' comparatively very long,r neck, which embraces the toot of the rail, and by it having a longitudinal web extending from the rear end of the dei vice to the bearing plate oi the Jfront of the same, so that the device is strongest at that part which is subjected to the `greatest stresses. However, 'the hook of 'the clamping boit adapted to engage the foot' of rail canbe so constructed that it only projects slightly beyond-the rail foot and only embraces the latter to suchv an extent that the'v clamping device can also Ybe used without alteration for rails carried by chairs and does not vhinder the insertion and withdrawal of the key for wedging the rail in the chair.,

The invention is illustrated in the accompanying drawing, in which` f In Figs. 1 and 2, c designates an ordinary railway rail having a broad foot b.

- In order to prevent` creeping of the rail a clamping jaw is detachably secured to the rail. This clamp, made of suitable material, such las a pressed plate of suitable thickness, comprises a long neck g embracing one side of the rail Jfoot l1 at the top and' bottom and, forming a broad channel which closely its this side of the vrail foot. The

front part of the narrow neck g is bentY lround toform a face whichis vertical to the yrail and forms a supporting or bearing face which is proportionally wide with respect to the rail ioctl.

which is preferably curved dpwnward at the front, or may be square instead, may project more or less at i beyond the bearing plate z.. ln the constructional example shown the front edge z' ot the neck does not project beyond the bearing tace 71 but is flush therewitlnor it may even be slightly set back, so that the plate 'it extending downward for an adequate distance always engages first when pushed toward the wooden or han sleeper d, andlbe'ars with a sufficiently large surface against the sleeper.

The bearing plate; e, ispreferably providedv underneath the neck g .with a recess 7c, which stitens the device. This recess inl may, however, Abe omitted, for instance in the case of a clamping device the neck g of which projects beyond the face iz.. The neck i g 'forms at the bottom a webplate o, which is parallel with the rai-l, and a prolongation of which forms the bearing plate it, at right angles to the plate/o, so that the latter t'orms a stil'iening rib. The stiiiening plate orenders the clamping device extremely strong at the most stressed part so that the device is capable of taking the greatest-strains and`- is consequently absolutely reliable. -s alreadyv mentioned, the whole clampingde vice is made in one piece. l

lIn proximity to the recess 7c the device is provided beneath the rail oot with ahole to receive a screw boltZ, one endv of which forms a hook m, which embraces the 'oppo- 'i .site side of the rail foot, while the other end is lprovided with nuts n, which bear against c the late o.' j

T e device is `placed 'on the rail oot 'in such manner that Vits bearing plate z bearsl y against thefsidc of thesleeper, whereupon the nuts "n *are tightened .up. The hook shaped screw bolt Z, m, with the aid ofthe nuts f/z., therrpresses the clamp 'firmly' against the rail, whereby the latter is'sov connected tothe clamp as to prevent'creeping of the with sleepers notA provided with' beveled edges all, in which case the face z' of the neck g would not project beyond .the bearing plate h but would touch the side'oi;4 the sl :.eper.v The clamping device can al'so'be employed with iron sleepers instead of Q mariees wooden sleepers, and is in fact applicable to any system of laying rails on sleepers.

In FiL 1. 3 and 4 showing the-.device ap- 'plied to a, 'rail carried by Chairs, a designates a socallerl bull lead rail having a narrow foot and a. slightly bigger head 1. This rail is secured in the known manner by a chair e on the sleeper d with the aid of a key The. clamping device itself is constructed in exactly the same manner as the device shown. in Figs. l and 2 and consists of one part g, h, i, o and the clamping bolt Z, m, n.. The hearing plate z., which bears With a sufiieiently large surface against the side of the sleeper a?, is about the saine Width the imirow foot b. The hook m, however, is in this caee so Shaped that it only engages ly over the top surface of the rail foot, inl its upper surface 7] only projects g'htly above the rail foot. The hook m, g) e( eqnently does not hinder the insertion or Withdiz, al ot' the key llliat l Gleim ae :ny invention is:

l. l railelanip, comprising an elongated Channel shaped neck adapted to partly einhmee ani/l one sifle of the font of a rail, a bearing plate depending from said neck at right angles to its longitudinal axis Lind adapted to bear against a Sleeper, a web connecting said neck and said bearing plate together, and a elal'i'iping bolt passing through said neck and forming a hook engaging the foot of the rail on the opposite side to that engaged by said neck.

2. A rail clamp, comprising an elongated .channel shaped neck adapted to partly embrace and engage one side of the foot-of a rail. a bearing' plate depending from Said neuk at right angles to ite longitudinal axis and adapted to bear against a sleeper.' a web connecting said nek and said bearing plate together, and a VClamping bolt passing through said neck and forming a hook engaging the foot of the rail on the opposite side to that engaged by said neck, said bearing plate having an inwardly depressed recess for lstrengthening the clamp. y ln testimony whereof hereunto alli): my signature in the presence of tWo Witnestes.
